The invention provides a hybrid power driving system and an automobile. The hybrid power driving system comprises an engine with a first shaft, a generator with a second shaft, a driving motor with a third shaft, a planetary gear mechanism, a first clutch, a second clutch, a brake, a first transmission mechanism and an output shaft. The first transmission mechanism is provided with a first connecting part which is used for being connected or disconnected with the first clutch; the first shaft is provided with a second connecting part which is used for being connected or disconnected with the second clutch; the brake is used for braking the gear ring. A hybrid power system adopting a brake and double-clutch gear shifting can realize a single-motor pure electric mode, a double-motor pure electric mode, a medium-low speed range extending mode, a medium-high speed ECVT mode, an engine direct drive mode, a hybrid parallel mode, an energy recovery mode and the like, and various working modes can adapt to different driving working conditions; the optimal working point of the engine can be optimized in real time when the vehicle runs, and the fuel economy can be improved.

    本发明提供了一种混合动力驱动系统及汽车。混合动力驱动系统包括具有第一轴的发动机、具有第二轴的发电机、具有第三轴的驱动电机、行星齿轮机构、第一离合器、第二离合器、制动器、第一传动机构,以及输出轴;第一传动机构具有第一连接部,第一连接部用于与第一离合器连接或断开;第一轴具有第二连接部,第二连接部用于与第二离合器连接或断开;制动器用于制动齿圈。采用制动器和双离合换挡的混合动力系统,可实现单电机纯电模式、双电机纯电模式、中低速增程模式、中高速ECVT模式,发动机直驱模式,混动并联模式,能量回收模式等,多种工作模式可适应不同行驶工况,使车辆能够在行驶时实时优化发动机最佳工作点,有助于提高燃油经济性。
